[access-uk] Re: Laptop system time resets

Two possibles:

1: 5 years is pretty much the lifetime of a BIOS battery.
but
2: It's odd that it happens when on, and googling around shows this
CAN happen when the timezone of the router is set wrongly.
I've summarized one of many threads mentioning the following:

Question: "Howdy, all. I have one machine in my office on which the
date and time will occasionally, at apparently random intervals, get
reset. Since it happens randomly and it is not my own machine I cannot
tell if it resetting to a specific date and time or if it changes. It
appears to change only the day, year and time while keeping the
correct month.
It is set to sync automatically and I have tried time.nist.gov as well
as time.windows.com. I have also tried resetting the date/time in the
BIOS and have changed the CMOS battery even though the time remains
correct after resetting or unplugging the machine for a few mintues. I
run anti-virus software continuously and have run mal-ware bytes and
spybot s&d to cover all the bases I can think of."

Answer:
"i'd say check your router for correct time settings and region settings."

Questioner responds:
"The router was indeed set to the wrong time and date. I didn't think
the machines would pull the info from there so I never worried about
keeping it current. I'm not sure why it was only affecting the one
machine, but I'm very happy to have it fixed."
